Creep

Description

The research group started its activity on the creep characterization of metallic materials on 1988. The materials investigated included light alloys (aluminum, magnesium and titanium), ferrous metals (stainless steels and high-Cr steels) and metal matrix composites. A major effort was focused on correlating the mechanical response of the investigated materials with their microstructural evolution.
